Symbol Table (Symtab)
|
|
#####################
|
|
|
|
The Symtab module, when enabled, will generate full symbol table during the Zephyr linking
|
|
stage that keep tracks of the information about the functions' name and address, for advanced application
|
|
with a lot of functions, this is expected to consume a sizable amount of ROM.
|
|
|
|
Currently, this is being used to look up the function names during a stack trace in supported architectures.
|
|
|
|
|
|
Usage
|
|
*****
|
|
|
|
Application can gain access to the symbol table data structure by including the :file:`symtab.h` header
|
|
file and call :c:func:`symtab_get`. For now, we only provide :c:func:`symtab_find_symbol_name`
|
|
function to look-up the symbol name and offset of an address. More advanced functionalities and be
|
|
achieved by directly accessing the members of the data structure.
|
|
|
|
Configuration
|
|
*************
|
|
|
|
Configure this module using the following options.
|
|
